GEORGE W. GRANIER. 0F RICHMOND HILL, NEW YORK.

QUOIN LOCK.

Application lcd May 14, 1321.

To all whom it may concern:

Be it known that I, Gnonon W. Giannina a citizen of the United States. and resident ot' Richmond Hill, in the county of Queens and itate of New York.y have invented cer tain new and useful Improvements in Quoin Locks, of which the following' is a. specification.

The invention relates in general to an improved form of printers quoin and particularly relates to a means Jfor locking' the Wedge members against relativiv movement when in position in the trame or lock-up.

Various means have been suggested for locking the Wedge members of a printer`s` lpioin but they have not been accepted in the trade due largely to the fact that the loi-king means project beyond the outlines of the traine and thus interfere with the staele ing ot the frames or make-ups or else the locking' features do not positively insure against slight crreping of the Wedge meinhers.

Accordingly, one of the objects oi" this invention is to provide a simple form ot lockirgg means Ator positively locking the meinhers in adjusted position so as to defeat any tendency of the wedge members from creeping and which Will be of such form as will not interfere with the stacking of thc frames and at the same time Will not weaken the Wedge members nor interfere with the impression while printing.

I attain this invention broadly by pivoting to the upper face of one of the wedge members a fiat spring plate, the free end of which is inturned to form a straight key dmiiiefued to have a snug' tit in one ot a plurality of closely positioned slots in the other wedge member.

Another obj-ect ot the invention is to provide a form of locking; means which can be readily replaced in case it is damaged and, above all the invention 'features'a construction which can be cheaply manufactured and marketed Without adding` materially to the present market cost of such devices.

Various other objects and advantages of the invention will be in part obvious trom an inspection ot the accompanying drawings and in part will be more fully set forth in the following particular description of one form of mechanism embodying my invention, and the invention also consists in certain new and novel features of construc- Serial No. 469,683,

tion and combination of parts hereinafter set forth and claimed.

In the accompanying; drawings Figure I is a plan view of a conventional torni ot printers quoin, showing a preferred embodiment of my invention in position thereon and With the lockingr elements in an inoperative position;

Figure 2 is a. view similar to Figure l with the locking elements in operative position; and

Figure il is a view in side elevation of the showing in Figure 2.

ln the following description and in the claims, parts will be identified by specific names for convenience of expression but they are intended to be as generic in their' application to similar parts as the art will permit.

In the drawings there is shown two Wedg- '7o ing: members 10 and 11 having interengaging inclined faces 12 and provided with shifting racks 13 designed to be engaged hy a shifting key 14 to move the wedge members longitudinally relative to cach other. Ho One side of each ot these members is idenY titled for convenience of expression as a top face, 15 and 1.6 which in such constructions are usually disposed in a single plane. It will be understood that the .structure as thus tar described is ot conventional form and is illustrated simply to show the adaptability of the invention to a conventional form ot printers quoin.

A broad fiat springr metal plate 17 is fas- 90 tened at one end by means of a rivet i8 to the broad end i9 of the member 1l. The opposite or .tree rnd 20 ot the spring plate is bent downwardly at right angles, shown in Figure 3, to form a straight lip 2l con- 96 stituting a long, rectangular key. The tace 15 is provided `vith a transversely extending;r straight slot 22 designed to receive one portion of the key as shown in Figure 3. The other face 16 is provided with a series 100 of transversely extending and longitudinally spaced apart slots 23 which slots are pret'- erably positioned relatively close together so that one of the slots 23 will be in alinement with the slot 22 practically in all rel- 105 ative positions of the wedging members. It will be thus seen that the key will tit snugly in the aligned slots and as the key is designed to tit in the slots practically Without side play any tendency of the Wedgingr mem- 2 i .fi-4

bers to move longitudinally will be resisted by the straight stiff key 21. It will be 11n-- derstood that even with the Wedge members in tight wedging positio s it is always pos sible to spring the containing` frame a little further, thus insuring the interlitting of the key in one or the other of the grooves. With the plate li' lixed rigidly in posir tion it is possible to move the key .simply by springing up the free end of the plate but the connection at 18 may be a. pivotal connection in which case the plate will first be raised to clear the key from the slots and then swung out of the way shown in Figure l, Which arrangement will permit the insertion. of the usual shifting key 14..

By means of a device oi this character it is possible to securely and permanently lock the Wedging members against movement and as the spring 17 is a Hat construction Jthere is no material interference with the print ing impression nor the stacking of the quoins and even the pivot L8 can be depressed below the slight projection shown in Figure 3. lt is possible to shift the plate .from the closed to and from the open posi tion shown in Figure l without rinsing this member materially vfrom the plane of the faces and this is of advantage i 'hen working within closely confined spaces.

llilhile I have shown and described` and have pointed out in the annexed claims, certain novel features of my inventioin it vill be understood that various omissions. sub stitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art Without departing from the spirit' oi the invention.

In a device of the class described, .l claim:

1. In a printers quoin, the combination of a pair of Wedge-shaped members havinlbr interengaging inclined faces, flat top sidrl i'aces and key-actuated racks constituting a part of means for moving the members rela tive to each other. a .latch pivotally mounted on the broader end of one of said flat top side `faces and having a downturned lip at its free end, the face to which the latch is pivoted provided with a slot for receiving a part oi said lip and the other top face provided With a slotfor receiving another part of said lip7 the engagement of the lip in both of said slots acting to prevent relative movement in one direction between the members.

2. In a printers quoin, the combination of a pair of wedginp; members, having top faces, each of said faces provided vvith an upwardly 'facing slot extending entirely across the same, said slots adapted to be moved with the members into alignment and a key fixed to the upper side of one o l` the members and adapted to fit snugly in both of said aligned slots to prevent rela` tive movement in one direction between 1hr members.

3. In a printers quon, the combination oil? a pair of wed ing members, one of said members provideV with a do'vvn-turned lip i'ormin` a straight key fixed thereto and the other member provided with a straighi` Slot rectangular in cross section and iashioned to have the lacy fit snugly therein and thus prevent any relative movement between the members in a direction transversely oi the length of the slot.

i. ln a device of the class described, the rombiimtion ol tivo Wedging members, a fiat plate pivoed ai one end to the upper side oi' one oi the members and provided at its free end with a down turned lip forming a key.i the other member provided with a series of slots each of which is designed to have the hey fitted therein to prevent relative movement between the members,

5. In a device o1 the class deerIibed.y the combination oll a pair of wedging niemberf. a one piece sprinpr plate secured at one end to one of the members and provided. at its free end with down-turned lip forming a heyy the other member provided with a slot rectangular in cioss-section i'or receiving the key and thus acting to )revent relative movement between the mem Jers.

(3. printers quoin formed. of four members. a pair oi' wedges, an L-shaped, Hat spring locking plate and a fastening means For securing one end of the locking plate to one oi". the members` the other member provided `.vith recesses ior receiving.y the free end of the spring locking plate.
